Trip Diagnosis
EEF
Internal EEPROM trip
Internal FXMP25 EEPROM checksum. When this trip occurs all the parameters are set to
default. The trip can only be removed by entering a load default command (i.e. Eur or
USA) into Pr 00 before re-setting the FXMP25.
FdL
No current in the field supply circuit
Check the field circuit.
Check the FXMP25 internal fuses.
FOC
Excess current detected field current feedback
Maximum field current is present.
Check the field rated current (Pr 70) and the field rated voltage (Pr 73) are set correct to
the motor nameplate.
Check for short circuit on field circuit cabling.
Check integrity of motor insulation.

O.ht1
FXMP25 overheat (SCR junction) based on thermal model
• Reduce ambient temperature or field current
• Check the fans are operating and venting is not blocked
O.ht2
Heatsink over temperature
• Reduce ambient temperature or field current
• Check the fans are operating and venting is not blocked
